The NX Stage 1 EFI nitrous system is the top of the line EFI power booster on the market. From the billet aluminum and carbon fiber solenoids, to our patented Shark nozzle, this system screams nothing but quality.

This system includes the latest technology and the best components available. NX Lightning solenoids feature an improved flow path that eliminates sharp turns and expansion areas in the nitrous flow path. This keeps the nitrous in dense liquid form which makes more power on less nitrous. Lightning nitrous solenoids feature an integrated purge port which allows you to connect a purge valve directly to the body of the nitrous solenoid for clean looks and less plumbing. Lightning Series solenoids feature CNC aluminum bodies topped with Carbon Fiber cans for the ultimate in weight savings.

The billet aluminum Lightning 45 bottle valve not only looks great; It is packed with features including an integrated gauge port, an integrated push port, a large .325 orifice and an improved flow path with only one 45 degree turn. The Lightning 45 bottle valve looks sexy, flows great and weighs nearly one full pound less than our old style NX 45 valve.
